To all 1i/)hom t may concern:

resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improvedy Cloth-Roller, of whichy the following is a description.

My invention relates to rollers on which rolls of cloth are wound and the invention while capable of wider use is more particularly intended for embodiment in the cloth rollers of sponging machines or like rollers on which the cloth is temporarily wound and from which the cloth must be drawn endwise 4of the roll. It is well known that with the ordinary roller in withdrawing the same endwise from the roll of cloth, the cloth at the interior of the roll is wrinkled and materially damaged, so that the damaged portion of the cloth constitutes a material waste.

The prime object of my invention is to provide a roller that may be withdrawn from the cloth roll Without any damage to the cloth.

Reference is to be had to the accompanying drawings forming a part of this specificati-on, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is an end view of a portion of a cloth sponging machine equipped with my improved cloth roller;

Fig. 2 is a side view of the roller;

Fig. 3 is a plan view thereof;

Fig. 4 is a view of the inner face of one half or section of the roller;

Fig. 5 is a similar view of the other half or section of the roller;

Fig. 6 is a broken longitudinal vertical section of the roller on an enlarged scale;

Fig. is an end view thereof; Y

Figs. 8 and 9 are respectively cross sections on the lines 8-8 and 9-9, Fig. 2.

In carrying out my invention in practice, in accordancewith the illustrated example, two similar` halves or sections, 10, 11, are provided and oppositely tapered so that their meeting faces are flat and present inclined planes oblique to the axis of the roller. Each roller section is provided at the broader end thereof with a trunnion 12 which is shown as square to take a crank handle for turning the roller which it will be understood in practice, may be turned y y y by hand or power in any ,suitable manner, Be it known that I, WILLLAM A. Ro'rnthe trunnion's` being adapted in the""case of noLz, a citizen of the United States, and `a the sponging machine A to rest in bearings 13.- Each roller section preferably is protected at the exterior by a metallic covering 14 usually of thin sheet brass.

On the inner face of one roller section 10 is a longitudinal track or guide plate 15 disposed centrally on said face and on the mating section 11 parallel tracks or guide plates 16 are secured, spaced to accommodate the guide 15. To the broader end of each section, 10, 11, is secured an annular band 18 which arches at the flat sides of the respective sections to accommodate the narrow or reduced ends 19 of hthe sections as best seen in Figs. 6 and 7. 4

By the described arrangement the sections 10, 11 are adapted to have relative longitudinal movement to engage the narrow end .of one in the ring 18 of the other section to complete the roller form and then with the cloth B wound on the roller, reverse movement of the sections to separate the same effects the withdrawal of the roller from the clothroll, without damage to the cloth, since the decreasing diameter of the roll proceeds from the initial relative longitudinal movement of the sections.

The rings in the example shown are braced by providing reinforced plates 21 on the respective roller sections and secured to the latter and to said rings 18. The smaller ends 19 of the roller sections are shouldered or rabbeted as at 17 to engage the rings 18 and limit the relative movements of the sections in an inward direction,

that is to say, to give the structure the cylindrical form. The tracks extend, at the ends of the sections, to the extreme ends to enter the rings 18 and to constitute a substantial reinforce for the wood bodies of the sections and thereby add a material element of strength to the reduced ends.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein` illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent: y

A roller of the class described including oppositely tapered mating sections separable by a relative longitudinal movement thereof',

an Y approximately central metal strip secured to ytlne inner face of one section, and parallel track` strips secured to the inner 'face of the other section spaced to accommodate the first-mentioned track; said sec- Y tionsloeing rabbeted at the reduced ends presenting shoulders, Vsaid tracks extending to Vthe extreme rabbetcd ends of the sections to reinforce said ends; together with bands on the Wider ends of the sections accomlnodating the rabbeted reduced ends of the sections and adapted to engage said shoulders, the ends of the tracks being aceommodated With said reduced ends in said bands When the sections are assembled.
